Fabian says the live fire demonstration shows how a single layer of added protection can literally change the face of security.

"We're protecting U.S., British, French, Canadian lives in the threat of war, but now that war has come home," Fabian said. "America is under attack, not just from terrorists, but from individuals who suffer from PTSD, individuals who have ulterior motives."

Advanced Coating Engineering, or ACE, has created a film that can make any glass bulletproof. They've been protecting military for years, and has now made the technology available for law enforcement and civilian consumers.

At the live-fire demonstration took place at the Poway Weapons and Gear range, bullets were fired at several glass windows varying in thickness. The unprotected windows shattered like a scene from an action movie, but the ACE protected windows, covered with just a thin film of ultra-strong material, broke but didn't shatter and the film caught the bullets.

Here's how the company says it works:

"It applies to polyester and the adhesives absorb energy and a kinetic force and it spreads across the whole surface of the window."

Instead of going through or ricocheting, the bullets get lodged between the adhesive and the glass, even giving investigators a forensic edge in the midst of a crime.

An approaching winter storm is poised to open an "atmospheric river" of subtropical rain clouds on Southern California this week, but the San Diego area is expected to see just a fraction of that moisture, forecasters said Sunday.
